Modulation Technique Direct Sequence Spread Spectrum -CCK,DQPSK,DBPSK(RevisionB)

-OFDM-BPSK,OFDM-QPSK,OFDM-16QAM,OFDM- 64QAM (Revision A, Turbo Mode)

The range of the wireless signal is related to the Transmit Rate of the wireless communication. Communications at lower Transmit range may travel larger distances.

❑The range of your wireless devices can be affected when the antennas are placed near metal surfaces and solid high-density materials.

❑Range is also impacted due to "obstacles" in the signal path of the radio that may either absorb or reflect the radio signal.

Supported Frequency Sub-bands

Subject to the radio regulations that apply in your country, your Wireless LAN Card may support a different set of 5GHz / 2.4GHz channels.

Consult your Authorized Wireless LAN or TOSHIBA Sales office for information about the radio regulations that apply in your country/region.
